The system ensures that both video streams are visible at the same time, enabling real-time comparison or monitoring of multiple sources. The display may be configured to arrange the video images in a side-by-side, split-screen, or other multi-view format, depending on the application. The invention may also include additional features such as synchronization controls, user interface elements for adjusting the layout, and options to prioritize one video stream over another. This approach is particularly useful in applications like surveillance, medical imaging, or video conferencing, where simultaneous viewing of multiple sources is essential. The system may further include processing capabilities to enhance the video streams, such as adjusting resolution, frame rate, or applying filters to improve clarity or reduce latency. The invention ensures that users can efficiently monitor or compare multiple video inputs without the need for separate displays or manual switching.
